41 * Note: The older util.php class simply printed a string, but the spec
42 * says that 500 errors should be treated similarly to 400 errors, and
43 * it's easier to give an HTML response. Maybe we can customize these
44 * to display some funny animal cartoons. If not, we can probably role
45 * these classes up into a single class.
